solver: merge apk_name_state to apk_name apk_name_state is now quite small; and we avoid overhead of two pointers (+ malloc overhead) when we just make it part of apk_name. It also fixes some problems (that got introduced) where apk_name_state was not allocated.

solver: rewrite as deductive solver -- core features Implementing basic dependency handling, install_if and awareness of pinning.

solver: add logic: transitive provides exclusion If name N is required, and all providers of A also provide B, it means that only instances of B can be selected that provide N. This is strong help with cases when so:libfoo.so.1 is updated to so:libfoo.so.2 and not everything is recompiled.

unsigned has_options : 1;
upgrade: new option: --latest (-l) Select latest version of package (if it is not pinned), and print error if it cannot be installed due to other dependencies. Together with --available, it selects the latest package which is present at least in some repository. This also fixes few solver issues with ordering of package selection that got quite apparent with this flag. Namely, we cannot "lock" a package until it's reverse dependencies are locked or not all of the solver flags are propagated properly.

unsigned reverse_deps_done : 1;
solver: consider virtual provides to exclude non-provides transitively this fixes package selection when a 'real' package exists, but would need to be provided by another package with 'virtual provides'. In current package database this can happen with postgresql which is also provided by postgresql-bdr. Normally postgresql would be satisfied by postgresql, but if any package depends on postgresql-bdr and there's no versioned dependency on postgresql this will help apk figure out that postgresql-bdr should be used.
